Отсутствующие плитки в Telerik TileList

Question

У меня есть 14 плиток в моем TileList (Telerik). Тем не менее, только 11 из них показаны на странице. Я не могу использовать пространство в правом нижнем углу области по какой-то причине. Есть идеи, почему это может вызвать эту проблему?

Answer 1

Решаемые. RadPersistenceManager был причиной. Он загружал состояние, которое было сохранено для 3 строк в Page_Load. Я изменил сохраненное состояние.
